PATENT JOHN J. SULLIVAN, F CINCINNATI, OHIO.

Application filed December 18, 1924. Serial No. 756,758.

To all whom it may aonbern:

Be it known that 1, JOHN. J. SULLIVAN, a

. citizen of the United States, residing at the Presses, of which thefollowing is a specifi-' cation.

The object of my invention is to provide an inking attachment for bedand platen job printing presses which will allow for the even, uniform,and constantly eflicient distribution of the printing ink, preparatoryto placing the same upon the type or form, readg for the printingoperation itself.

I ispense with the usual ink carrying circulating disc well known in theart in this form of printing presses, and provide a plate usuallysemi-cylindrical in contour which I call a vibrating distribution,plate, which vibrates forwardly and backwardly upon which ink isdeposited and I provide means for thoroughly, evenly and uniformlydistributing the ink thereon, forming a film of ink thereon whichwill'produce a film of ink of the same density and thickness,throughout, which is transferred to the inking rollers which place thesame upon the typeor form, ready for the printing operation 1tself,insuring an even and uniform application of ink to the type, plate orcut being used.

In order to thoroughly distribute the ink and place it uniformly andevenly upon the distribution plate, my distribution plate vibratesforwardly and backwardly and 3 presses against the rollers which carrythe ink, theserollers remaining stationary and in this manner thedistribution plate by its vibrating action takes the proper amount ofink 03 of the rollers, hence it is evenly distributed on said plate.

My attachment is simple, highly efiicient in operation and dependablefor uniform work, possessing great utility.

Itis a well known fact that in order to do a, good job ofprinting, theink must be evenly and uniformly distributed so that the printing itselfwill be of a standard, uniform, and even appearance upon the paper 11 onwhich the printing is done, so as to be "p easing to the eye and showgood workmanship in its appearance.

With my attachment I overcome any defects nowjpresent in the bed andplaten printing presses now used, as to the proper distribution of theprinting ink.

Thevarious features and advantages of my invention will readily becomeapparent from a perusal of the following specification and claims.

In the accompanying drawing forming part of this specification:

Fig. 1, is a view in elevation of a printing press, showing my device inposition,

Fig. 2, is a rear view in elevation of my device,

Fig. 3, is a side elevation of one side of the device,

Fig. 4, is a view in elevation of the other side of my device,

Fig. 5, is a plan view of the device, and

Fig. 6, is an enlarged plan view of the cam lever and its connectingworking parts.

In carrying out my invention as shown in the drawing, I illustrate anoutline of a bed or platen job printing press in order to betterdescribe m device or attachment.

Located in the side frames 1 of the printing press, is the shaft 2, onwhich I pivotally mount one end of the roller arm 3, the other end ismounted to an arm 4 mounted on a rock shaft 5, which is supported by thebeams 6, the beams being in turn, held securely in the rocking bed 7 ofthe printing press. Mounted on said shaft, at both ends, are the sideplatesj8, 8, and at their upper edges 9 I place the semi-cylindrical,vibrating curved ink distributing plate 10.

On both sides of the distribution plate 10 I place the curved bracketsor guards 12, 12, one end of which is fastened in the beams 6, at point13, the opposite end being fastened to the rocking bed 7 of the printingpress, at the point 1st.

On the brackets 12, I place the auxiliary brackets 15, in which I mountthe shaft 16; at one end of Said shaft I place the roller link 17 'andthe hpposite end of said shaft 16 is mounted in one arm of cam lever 21which link 17 and lever 21 carry the ink feed roll 19, which is mountedon the shaft 20, one end of which shaft being mounted in the cam lever21, which is pivotally mounted on the stud shaft 22, supported hy thebeam 6. In the upper extremity of the arm 23 of the cam lever 21, Ipivotallv mount the cam roller 24, which engages t e cam 25, mounted onthe side 8'. A recessed portion 26 of distributes it over the I end ofthe lever 29 I mount one end of the rocker arm 30 and at the other endof said rocker arm 1 plvotally, mount the pawl 31;

this pawl engages the ratchet 32, which is mounted on one end of theshaft 33, said shaft being securely mounted in the rocker arm 30, nearits center.

The shaft 3; also carries the ink roll 34: which is located in the inkfountain 35.

Mounted on the brackets or guards 12 are the ink distributing rolls 3U,37, 38 and 39 and between these rolls is the agitator vibrating roll 40.These rolls are of the usual form now well known in the art, andneed notbe further described.

On the ink fountain 35 I'provide the adjusting screws 41, theyregulating the sup ply of ink and as they are well known in the art,they need not be further set forth.

I will now set forth the operation of my device or attachment asconnected to a .bed or platen job printing press. As the rocking bed 7of the printing press rocks backwardly andforwardly, the lever arm 3rocking on the shaft 2, which is held stationary in the side frames l ofthe printing press causes the distribution plate 10 and the side plates8 and 8 to rock back and forth on their shaft 5 by reason of small arm 4being connected to the lever 3. It will be seen that when the bed 7moves backwardly and forwardly with one end of lever 3 held stationaryand the other end connected to the arm 4, mounted on shaft 5, said shaft5 being carried by the bed itself, a rocking action will take place,with the distribution plate 10. In other words, said plate 10 will be.vibrated.

As the distributing plate l0 vibrates or rocks back and forth, the plate8 carrying the pin 27, which riding in slot 28, after having reached itslimit of travel, said pin 2-7 will carry with it the lever 29, causingthe pawl 31 to ride backward through medium of link 30 so that when thedistribution'plate 10 returns, and the pin 27 return to its limit oftravel at the opposite end of the slot 28, it carries said lever 29 withit. to a predetermined point, causing the ratchet 32 to revolvethe inkroll 34;, through the medium of the lever 30 and the pawl 31.

As the distribution plate 10 rocks or vibrates back and forththe camroller 24 engaging cam 25 at the recess 26 allows the feed roll 19 totake its supply of ink from the intermediate feed roll 42, which, inturn, late 10, when the roller 24 passes out of t e reccss'26 on the cam25, allowing the feed roll 19 to contact with. the vibratingdistribution plate 10 as said plate passes underneath the roller 19. inorder to keep the even distribution of ink on plate 10, I also providethe agitator rolls 36, 37, 38, 39 and 40. These rolls are well known inthe art and need not be further described.

' The rollers 50, there being three in the present" instance, are theones which take the ink off of the distribution plate I0 and tranfer itto the form having the type or printing matter thereon, see Fig. 1. Thedistribu tion plate 10 vibra es forwardly and baclf wardly and vibratesbackwardly to receive a fresh supply of ink and then moves forwardly andas it moves forwardly the rollers 50 which place the ink upon the formcarrying the type moves up on its face to receive the fresh ink, andwhile said roll ers :30 are moving downwardly to place said ink upon theform carrying the type, the distribution plate 10 is moving backwardlyto receive a fresh supply of ink and this movement is kept on as long asprinting is being done.

Through the medium of adjusting screws 41 more or less ink can beallowed to pass upon the distribution plate 10 as desired and in thismanner a film of ink upon said distribution plate may be heavier at onepoint than at another. This being the case when more ink is desired tobe placed upon the printing form at certain places. example, if a sheethad to be printed with light small type at one end and havinglar e anddark typeat the opposite end of s id sheet, then I would place more inkon the distribution plate at the point where the large type would comeon the sheet when printed and less ink where the small letters wouldcome. during the printing process;'a better, superior and moreWorkmanlike job would result, and the appearance of the printingenhanced. The ink would be evenly distributed under these conditions,except that more ink would be distributed atone point than at the other,but it would be distributed evenly for this job and every separate sheetprinted. From the foregoing, it will readily become apparent thatvarious colors may be applied to various areas extending longitudinallyof the elongated face of the distribution plate, whereby a multicolorprinting job may be handled on a job printing press, care need only betaken to prevent overlapping of colors.

The distribution plate 10 may be of other form or contour than hereinspecifically shown and described and I may support For any

it-in position in any other manner to form and carry out the vibratingplate as described. i

is a preferred one, but I may deviate-from eer "nor a the same andmodify it. so long; as it falls w'ithin the scope of this specificationand. claims. v
